<form Name="Advanced" method="POST" action="https://www.oxhp.com/cgi-bin/provider_roster/avsearch/avsearch_ch.pl">

<input type="text" name="SearchFor" value="Doctor" />
<input type="text" name="lang" value="cn" />
<input type="text" name="_DOCTYPE_TEXT" value="" />
<input type="text" name="_SPECIALTY_TEXT" value="" />
<input type="text" name="_NETWORK_TEXT" value="" />
<input type="text" name="_MILES_TEXT" value="" />
<input type="text" name="_STATE_TEXT" value="" />
<input type="text" name="_LANGUAGE_TEXT" value="" />

上面的是需要传的搜索参数,我应该怎么抓取?

 System.Net.WebClient wb = new System.Net.WebClient();
            System.Collections.Specialized.NameValueCollection param = new System.Collections.Specialized.NameValueCollection();
            param.Add("SearchFor", "Doctor");
            //...
            byte[] b= wb.UploadValues(new Uri("https://www.oxhp.com/cgi-bin/provider_roster/avsearch/avsearch_ch.pl ",param));
            //...

最好用httplook看看，WebClient 可以完全伪装成ie

然后怎么写？小弟是新手，不懂，可以再说清楚一点吗？

[a11377815]

public class TrustAllCertificatePolicy : System.Net.ICertificatePolicy
{
public TrustAllCertificatePolicy()
{ }

public bool CheckValidationResult(ServicePoint sp,X509Certificate cert, WebRequest req, int problem)
{
return true;
}
}

protected void Page_Load(object sender, EventArgs e)
{
System.Net.ServicePointManager.CertificatePolicy = new TrustAllCertificatePolicy();


string backstr = "";
string param = "SearchFor=Doctor&lang=cn&_DOCTYPE_TEXT=Primary Care Physician 主治醫生/OBGYN婦科醫生&_SPECIALTY_TEXT=Pediatrics 兒科&_NETWORK_TEXT=Freedom&_MILES_TEXT=5 英哩&_STATE_TEXT=New York 紐約州&_LANGUAGE_TEXT=Any&_ZIP=11220";
byte[] bs = Encoding.ASCII.GetBytes(param);

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("https://www.oxhp.com/cgi-bin/provider_roster/avsearch/avsearch_ch.pl");
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = bs.Length;

using (Stream reqStream = req.GetRequestStream())
{
reqStream.Write(bs, 0, bs.Length);
}
using (WebResponse wr = req.GetResponse())
{
StreamReader sr = new StreamReader(wr.GetResponseStream(), System.Text.Encoding.Default);
backstr = sr.ReadToEnd();
sr.Close();
wr.Close();
}

Response.Write(backstr);
}

还是得不到东西啊！郁闷死了！

当你获取HTML的时候再用MILHTMLParser（到网上下载一个，开源的）来分析你的HTML
获取你想要的
